Select the structure that corresponds to the molecule name:

Option B

Explanation:

The name of the molecule is;

1,1,1,3,3,3-Hexachloropropanone

Now, we can see that it contains propanone which is also called acetone. So it will have a double bond with Carbon(C) and Oxygen (O).

Option B has that double bond between C and O that indicates it propanone or acetone.

Thus, it is the correct option.

the volume increases

the answer is b. dilution
